Summary
| Description |
English: The Soul Nebula (Westerhout 5 or Sharpless 2-199), that is seen on the photo as colorful patch above, is an emission nebula located 7500 light years away from Earth in constellation Cassiopeia. Several small open clusters are embedded in the Soul Nebula. The object is more commonly called by the star cluster designation IC 1848.
The Heart Nebula (IC 1805 or Sharpless 2-190) is also an emission nebula located in constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It displays glowing ionized hydrogen gas and darker dust lanes. Subframes for the photo was taken from Estonia. Stacked image is post-processed in so called HOO palette, where different wavelenghts has been assined different colors. Photo processing technique know as Drizzle (2x) has been used to increase the resolution of the original image. Technical details:
Eesti: Hinge (ülal) ja Südame udukogud Kassiopeia udukogus. Need kannavad vastavalt IC 1805 ja Westerhout 5 tähiseid ning asuvad meist umbes 7500 valgusaasta kaugusel. Tegelikelt mõõtmetelt sadu valgusaastaid laiad vesiniku, hapniku, väävli ja kosmilise tolmu pilved hõlmavad taevas mitme täiskuu ketta laiuse ala ning need on paigaks, kus kosmilisest gaasist kukuvad gravitatsiooni mõjul kokku uued tähed. Juba tekkinud noored ja kuumad tähed ergastavad udukogusid seestpoolt, pannes need erinevates lainepikkustes helenduma. Näiteks Südame udukogu (all) keskel on hästi näha noort hajustäheparve Collinder 26, mis sisaldab sadu noori tähti, millest mõned ületavad Päikese massi 50 korda ning on viimasest miljoneid kordi heledamad.
Foto jaoks vajalikud kaadrid on tehtud Eestist Tõrva linna taevast ning foto on töödeldud võltsvärvidesse (HOO). Foto resolutsiooni on suurendatud läbi nii-nimetatud drizzle (2x) tehnika. Kasutatud tehnika:
